Question 1

So is brushless better than the regular DW drill??

Accepted Answer

Yes. First off, it is more efficient than brush-ed. When you run it with a light load, it draws less power. Dewalt says you get up to 30% more runtime from the same charge.  The better efficiency is a fact, and the 30% is possibly conservative.  There is a youtube video of a guy drilling 1/2" holes into a board with a brushless and a traditional dewalt drill, and the brushless wins 2 to 1.  it drills some 190 holes vs the brushed just 92.  The second advantage: there are no brushes to wear out and replace.  TBT I have  many brush-ed tools and as a DIY-er I never had to replace the brushes on any of them, but this may be an advantage to a pro or heavy user.  A third advantage, the tool can be built more compact, or more powerful (given the same size)The only advantage of the "brush equipped" design:that it is simpler.   The brushless  changes the direction of the Dc current  using electronics instead of a mechanical commutator, so that is an extra source of possible failure

Question 2

Why do two Lithium ion batteries go for $170. and the kit with two batteries a charger the carry case and the drill go for $97.00

Accepted Answer

Unfortunately, nowhere on the box am I able to find amp hours and when asking Lowes employees they said it was 20 volts.  I had to explain that I am needing to know amp hours.  It took me awhile to find online that the batteries in this kit are 1.3 Ah.  Even in this Amazon ad the only place I have found it mentioned is in the questions.  The batteries that were 2 for $99 at Lowes were 3Ah.

Question 3

How long does battery last

Accepted Answer

Batteries that come with unit are small but very light, excellent for my usage. DeWalt sells these 20v packs in 3 different capacities these are the smallest ones. How long they last is a HUGE variable based on what the task is so that will be impossible to determine for someone else. In my experience these small ones last about the same as the 18v Ni-Cad Dewalt system (18 yrs old) I replaced with this set.

Question 4

Does this have a battery life meter on it?

Accepted Answer

It does not have a battery life meter.  It does come with two batteries so it's not to big of an issue.
